'1 0 all (U/107T!- izf may concern:

Be it known that I, PAUL Mnnnoci-r, a citizen of the United States and residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Railway-Rail Joints, of which the following is a specification.

This invention relates to railway rail joints.

The object of the invention is to provide a structure of this cha 'aeter Which shall be thoroughly eifective in holding the meeting ends of two rails in positive alinement, and in which loosening of the fastening means of the fish plate will be reduced to a minimum whereby accidents resulting therefrom will be eliminated.

Another object of the invention is to provide a structure in which the necessity for bolt holes. usually six of them in the ends of the rails is eliminated.

\Vith the above and other objects in view as will appear as the nature of. the invent-ion is better understood, the same consists in the novel construction and combination of parts of a railwayrail joint, as will be hereinafter fullv described and claimed.

In the accompanying drawing forming a part of this specification and in which like characters of reference indicate corresponding parts: Figure 1 is a view in side elevation of a railway rail joint constmcted in accordance with the present-invention. Fig. 2 is an inverted plan view of the joint. Fig. 3 is a transverse sectional view taken on the line 33, Fig. 1. at is a perspective view of one of the fish plates. Fig: 5 is a perspective view of the bolt and clamp utilized in holding the fish plates assembled on the rails. Fig, 6 is a view inside elevation like Fig. 1, of a slightly modified form of construction. Fig. 7 is an inverted plan view of the form of construction. shown in Fig. 6. Fig. 8 is a transverse seetional view. taken on the line 8-8 of Fig. 6. F ig. 9 is a view in perspective of one of the fish. plates of the construction shown in Figs. (3 to 8. Fig. 10 is a perspective view of the bolt. and clamp utilized in holding the fish plates of the construction shown in Figs. (3 to 9 assembled on the rails, and, Fig. 11 is a transverse vertical sectional view of a. still further modified form of fish plate.

Referring to the drawings and to Figs.

l 5 thereof, Ll designates the treads of two rails which may be of the usual or any preferred construction, XV, the web thereof, and

B, the base. The opposed ends of the two rails as usual, are supported by sleepers S whiehniay be disposed as shown, or otherwise.

The feature of the present invention resides in a novel form of fish plate the construction of which is such as to insure that. the meeting ends of the rails will be maintained inabsolut'e alinement, and that accidental diseonneetion of the fish plates from their intended position will be eliminated and that it Will not be necessary to drill holes for bolts in. the ends of the rails, is done in the present system of railway rail joints. In order to secure this result, each fish plate is provided with a shoulder 1 to rest against the under side of the tread with a longitudinally channeled web 9. to bear against the like portion of the rail, with a base 3 to rest upon the like portion of the rail, with a flange l'to overhang the edge of the base of the rail, and with an intermediate seat 5, forming a continuation of the flange 4i and arranged to embrace onehalf of the base and to extend beneath the same, the like portions of the rail on its opposite side being similarly guarded by a fish plate, a counterpart of the one just described. The seats 5 rest. upon a sleeper U so that the depression of the rails at their meeting points is obviated and unnecessary strain upon the fish plates is obviated. The fish plates are held assembled withthe ails primarily by spikes 6 which operate in the usual manner of such at tachments.

As shown in F 2, the opposed faces of the two seat members are provided with oppositely-(iisposed interlocking saw toothed shoulders 7 which are designed to prevent lateral displacement of the fish plates and the latter are firmly held assembled by bolts 8. The manner of combining these bolts with the fish platcsto guard a sible, against their detachindm 'iutvibrzu tions or other causes, from. the plates, con-- sists in providing one end of each bolt with a. clamp-9 having a too 10 that is designed to overlie the edge of the rail base where the latter extends through a slot formed in the base 11 of a recess 19. provided in the outer face of the web 2, a removable clamp 12 beingdisposed upon the end hf the bolt opposite that carrying the clamp 9 and be ing held assembled therewith by a nut 13 serving to complete the clamping means. It is designed that the two clamps shall be housed within the recesses 12 iormed in the outer faces of the bosses Qcf the webs 2. as shown in Fig. 3, so that any lateral turning of the clamps will be positively precluded. Said bolts may be put in, 2'. 6., their heads used, from either side of rail. The shanks 8 of the bolts puss beneath the bases of the rails, thereby rendering unnecessary any changeor alteration of the rail to adapt it to receive the bolt. As a further means of 15 obtaining a positive assemblage of the fish plates with the rails, a bolt 1% is employed v Which passes through the fish plates, the opposed ends of the rails being provided with seats 14 to receive the bolt which is firmly locked in position by a nut 15.

In the form of the invention shown in I Figs. 6 to 10, the same principle of interlock of the fish plates is involved, the ra" seat 5 of each fish plate however, extending throughout the length of such fish plate, and the integral clamp or head Si on bolt 8 is flat faced and abuts against the edge of the rail base as shown in Fig. '8 instead of 'being provided with a nose to engage over the rail base, as in the construction shown in Fig. In other respects the construction of the parts being the same, like numerals of reference have been applied thereto.

In the form. of the invention shown in Fig. 11, the fish plates 16 have at their lower edges, flanges 17 that engage around the outer edges of the base or the rail, the plates being held in position relative to the rail. by 40 means of a clamp 18, the ends of whieh'are bent around the flanges 17 of the fish plates, and project. a s uliicient distance toward the web of the rail to insure the retention. of the clamp in position. It will be noted that the fastening means in all forms-of the inven tion, namely, the bolts 8 in l igs. l5., the bolts S in Figs. 6 to 1'3, and the clamp 18 in Fig. 11 pass beneath the rail base and embrace or engage with the fish plates on a plane above the upper surface of the rail base. The bolts 8 and 8 are shown as insertcd from opposite sides of the rails. Obviously, they may be inserted from the same side if desired. In the construction shown in Figs. .1 to 5, the nose 10 engaging over the rail base serves as an additional clamp to securely hold the parts.

VVhile' the improvements herein described are simple in character, they will be found eer gee? thoroughly ef'licient for the purposes designed, and will co-aet in the production of a thoroughly etlicient and reliable form of railway rail joint.

What I claim as new is 1. A railway rail'joint without the usual holes in the ends of rails and without the bolts to engage in those holes, comprising two fish plates having extensions constituting rail seats to pass under the bases of the rails and to be interlocked and means for securing the fish plates in locked relation relative to the rails and for preventing 10ngitudinal movement of the fish plates and rails relative to each other.

2. A railway rail joint without the usual holes and bolts in ends of rails, comprising two fish plates having extensions constituting rail seats to pass under the bases of the rails, the opposed faces o'f'the seats" being provided with angularly-disposed shoulders arranged to be interlocked by longitudinal movement of one seat relative to the other, and means for securing the fish plates in locked relation relative to the rails and for preventing longitudinal movement of the fish plates and rails with regard to each other.

3. A railway rail joint without the usual holes and bolts in the ends of rails, comprising two fish plates having extensions constituting rail seats to pass under the base of the rails and to be ii'iterlocked, each of the seats being provided on its outer side with key-hole-shaped recesses, and bolts iassin throiwh the seats and havin s el 13 b cial. heads on one end engaging in the re cesses in the seat of onev fish plate, and keepers on the opposite ends of the bolts engaging in'the recesses in the seat or" the other fish "plate.

railway rail joint without the usual holes and bolts in the ends of the rails, c'onr prising two fish plates having extensions constituting rail seats to pass under the base of the rails and to be interlocked, each of the seats being provided on its outer side with he -holessha'ped recesses, and bolts with special heads passing through the seats and having keepers engaging the recesses, the bolts being disposed beneath the bases of the rails.

In testimony whereof I a'llia; my signature in presence of two witnesses.
